As a result of growing demand, Couplemate commenced the manufacture of all ball sizes. Our largest truck ball size is 3? for our 10t gooseneck coupling.
We also found many Chinese balls do not pass AS4177.2. Therefore, compliance standards are not met; as a result, strict penalties and loss of reputation for offending companies are costly.
To ensure compliance with the regulations, Couplemate manufacturers and tests our towing equipment.
Finally, if you need us to manufacture custom towing appliances, give us a call on 07 33483822. We also stock a tow ball collar for 10t couplings.
